SES (Simple Electronic Signature)

The Simple Electronic Signature (SES) is the basic level defined by the eIDAS regulation. It requires no specific technical requirements: an 'I accept' click, a signature image or an email signature satisfies it. Its evidentiary value is presumed but can be challenged if the signatory denies their act. It is suitable for documents with low legal risk (quotes, internal minutes, agreements in principle). For important stakes, prefer the AES or QES level.
